Although described as regular dies trial pieces, these were deliberately struck for sale to collectors as part of complete off-metal sets.

Examples were struck as follows:

Copper J1255. This is unlisted in Pollock. One example weighing 43.98 grains was found to be 99.4% Copper and 0.6% Aluminum. Others are probably masquerading as a regular issue proof.

Aluminum J1256/P1397 with only 2 or 3 examples believed to exist.

Nickel J1257/P1398 and illustrated below. The illustrated piece is a business strike, not a proof. We believe this piece is actually a mint error struck either on a planchet intended for a foreign coin, a nickel 3 cent planchet, or nickel stock, for either nickel 3 cent or shield nickel stock which was miscut into cent planchets.
